Patent application title: NOVEL WATCHCASE ASSEMBLY

Abstract:

A watchcase is provided including a watchcase and an exoskeleton. The
exoskeleton is aesthetically pleasing and engineeringly sound,
encompassing the watchcase and protecting it from everyday wear and tear,
of which it could be totally independent from the watchcase or could be
attached to the watchcase in a supportive manner with connectors
attaching it to the watchcase and connected with screws and separate
supportive parts, reinforced from the exoskeleton mainframe to the top of
the watchcase. The supports or connections could be engineered to evenly
distribute any stress points, creating a ridged protective barrier for
the watchcase.

external perimeter and an internal cavity, said cavity being sized and
shaped to receive a watch movement; andan exoskeleton sized and shaped
around said periphery to protect said watchcase, said exoskeleton
including a ring and connectors extending between and attached to said
ring and said watch case,

[0004]2. Description of the Prior Art

[0005]Wristwatches, and specifically watchcases, are manufactured to
protect the watch movement and conversely produced in shapes and designs
that are aesthetically pleasing and saleable to the consumer marketplace.
Watchcases are produced from various metals that have different strengths
and durability for different environmental conditions. Several metals and
alloys are well know in the industry that are particularly suitable for
wristwatch cases because they are suited for this purpose including
stainless-steel, such as, 904L or 316L, as well as various platinum and
gold alloys. Any wristwatch actively worn is subject to wear and tear
over the year. This invention relates generally to a protective barrier,
or exoskeleton, on the outer perimeter of a wristwatch case.

[0006]Historically, watchcases are designed to serve as protection for the
inside of the watches caliber or movement complications as described in
U.S. Pat. No. 4,068,464, Barnett. During World War 1, early military
wristwatches used protective grilles over the dials while other models
have faces that are changed by sliding the case dial, reversing to a
metal cover. Other means of protection include the use of flexible
substrate that has an extended flap, as described in U.S. Pat. No.
6,199,730 B1, Chisolm, and U.S. Pat. No. 6,799,887 B1, Kinney. Other
means include an entire encompassing of the watchcase with a hardened
substrate, as described in U.S. Pat. No. 3,643,423, Piquerez, or a
shutter device described in U.S. Pat. No. 5,805,535 Guyard et al, and
U.S. Pat. No. 6,739,748 B2, Della Santa or even a watchcase inside of a
watchcase as described in U.S. 2006/0034161 A1, Muller or U.S.
2008/0074958 A1, Moran. In these references, protection either restricts
the aesthetic appeal of the wristwatch or exaggerates its protection
verses it wear ability.

[0007]The following concepts comprise various aesthetic and function
ability and therefore improvements to the basic patents or patent
pending, of these inventions.

SUMMARY OF THE INVENTION

[0008]A feature of the present invention that is an improvement over the
prior art provides watch case assembly constructed and arranged to
protect watchcase from abrasions and impact.

[0009]It is further feature of the present invention is that it provides a
watch case assembly including an exoskeleton that could be circular to
match the outer perimeter of a standard watchcase or could have other
creative shape to accommodate and match the shape of a wristwatch.

[0010]Another feature is that provides exoskeleton protection that allows
the wristwatch case to be made from softer materials such as gold or
plastics and which can be power coated, or painted in fashionable colors.
The watchcase assembly can be painted and clear coated like an automobile
but can protect the watch from direct impact therefore reducing chips and
scratches.

[0011]More specifically, the present invention provides a watch case
assembly including or incorporating a protective exoskeleton attached to
a watch case. In a preferred embodiments includes "0" ring shaped body
and several connectors used to connect and mount the ring to the case.
The connectors are coupled to the ring and the case by traditional
coupling means, such as screws, and the like. These connectors are
preferably designed and constructed to distribute stress and impact
evenly throughout the structure.

[0012]More specifically, the present application pertains to an
exoskeleton which could be in the shape of a metallic ring, an "O" ring,
that is aesthetically pleasing and sound from engineering view. The case
encompasses the outer perimeter of a watchcase, protecting it from
everyday wear and tear, and independent from the watchcase or could be
attached to the watchcase in a supportive manner with cantilevers
stretching from the surface and leading underneath the watchcase,
connected with screws and separate supportive parts. The supports or
connections could be engineered to evenly distribute any stress points,
creating a ridged protective barrier for the watchcase.

DETAILED DESCRIPTION OF THE INVENTION

[0020]As shown in the Figures, a watchcase assembly 10 having a watchcase
12 with a body 14 having a top surface 16 defined around a cavity 16 with
a bottom wall 17. The cavity is sized and shaped to receive a standard
watch movement. Once the movement is placed in the cavity 16, a crystal
is placed on the top of the movement and affixed to the watchcase to
protect close the cavity and protect the movement.

[0021]The watchcase 12 further includes two lugs 18, 20 extending away
there from. Each lug includes two generally parallel arms 22, 24 and a
pin 26. As discussed later, the lugs are used to affix a band to the case
in a standard manner. The lugs may further include additional arms 28
that provide further strength to the lugs, or merely to provide some
additional aesthetic elements.

[0022]The assembly further includes a protective exoskeleton formed of an
outer ring 30 and a plurality of connectors 32 mounting the ring 34 to
the watchcase 12. Two kinds of connectors are provided: a short connector
32 that extends between and is attached to the top surface 14 of case 12
and the top surface 15 ring 30 and a long connector 34 that has one end
attached to the top surface 14 of the case and the top surface 15 of the
ring, but then continues downward around the ring 30 and extends radially
back to the case 12 where it is attached to the bottom surface 19 of
bottom wall 17. In one embodiment, the long connector 34 could be formed
of two sections: a top section 34A having the size and shape of short
connector 32, and a bottom section 34B that is generally L-shaped as
shown. The two sections are joined by soldering or other similar methods.
Preferably the connector is made from a single piece.

[0023]The connectors 32, 34 can be attached to the case and/or ring by any
well known means. In the Figures, the connectors are attached to the case
by appropriately sized screws 40. Since the lugs 18, 20 extend radially
past the ring 30, they are also attached to the ring by screws or other
means to provide added extra strength and rigidity to the exoskeleton.
Moreover, notches as at 44 may be provided in the lugs to receive ring
30. Preferably, screws 48 are inserted from the bottom surface of the
lugs and extend through the lugs and into respective threaded holes in
the ring 30 thereby securing the ring 30 to the lugs, as shown in FIG. 5.

[0024]In the embodiment shown, the ring 30 has the same shape as the
watchcase 12 and follows its perimeter fairly closely so that there is an
even annular space formed between the ring and the watchcase. Of course,
the two parts need not have the same shape. Either, or both can have
round, oval, rectangular, octagonal or even random shapes, etc.

[0025]The advantages of the exoskeleton are obvious to one skilled in the
art. The exoskeleton provides a bumper zone that protects the watchcase
12. As a result, the watchcase can be made of softer material, such as
gold layering, gold IP, rubber or painted with a clear coating, since it
will be protected from scratches or dents by the exoskeleton. The
exoskeleton is preferably made of a much harder, more durable material,
such as a 904L or 316L stainless-steel.

[0026]FIG. 6 shows a slightly different embodiment of a watchcase assembly
complete with movement. In this embodiment, the movement 60 is provided
in the cavity formed in the watched case and a standard crystal (not
shown) is installed on top to protect the movement. In this embodiment,
connectors 62 (having the shape of Roman numerals) and straight
connectors 64 are used to join the watch case to ring 30. Moreover a
watchband 66 is also added to complete the watch.

[0027]Obviously numerous modifications may be made to the invention
without departing from its scope as defined in the appended claims.
